A new series of optically active dopants have been prepared using 4,4”-terphenyldicarboxylic acid and 2-alkanols. These are nonmesomorphic, chemically stable—especially with regard to racemization and UV-light-compounds. Introduction of such a compound into a smectic C matrix of phenylpyrimidine or phenylbenzoate type leads to broadening the smectic C range of the matrix despite the fact that the dopant itself is a nonmesomorphic compound. The Ps value induced by the dopant depends greatly on the length of the alkyl tail attached to the chiral center from the external part of the molecule. |
